It’s Char Aznable from Gundam 0079 and other Universal Century Titles.
Char Aznable is one of the most complex characters I’ve ever seen. Not to mention the number of names he had during his life. From Casval Deikun to Eduardo Mass to Char Aznable to the Red Comet and finally Quattro Bajeema. I won’t tell you the specifics of why, but it has a lot to do with revenge and hiding in plain sight.
Char was an amazing pilot before he even had any glimpse of New Type (special human) abilities and his role as the antagonist to the main character of Gundam 0079, Amuro Ray, is truly compelling. I don’t know if I explained him well enough, but there is a reason why there is so many Char clones in the Gundam franchise, though few get close to level of awesome of the original.
